Thinking about it, I think what makes may father a man, isn't the fact he's a barrel chested brick wall, or that he can fix a 205 engine with, "some old piping in my desk", chop wood with his bare hands but actually it's the fact that he "has no need for these modern road direction machine things" (satnav), instead choosing to install a spherical compass to the dashboard and 'guessing' the right direction by his own senses, the position of the sun and the poles of the earth.
